I didn’t think so, until I read this at the Torontoist blog, which said that:
District 9 was directed, written, edited, and scored by Neill Blomkamp, Terri Tatchell, Julian Clarke, and Clinton Shorter, respectively—all Canadians. (Blomkamp was born in South Africa but moved to Canada as a teenager.) The film, however, was produced by Peter Jackson’s Wingnut Films (New Zealand) and financed by QED International (USA).
I think it is a great film, period. It’s good to see so many Canadians on it.
